C ++ exercises have solutions (sample code)
Besides the Python, Java exercises, TipsMake.com also summarizes for you some basic C ++ exercises to practice more in the process of learning C ++ programming language.
This C ++ exercise list is divided into 9 sections, each with 3 to 5 items, with increasing difficulty levels. Initially you will "boot" with very basic C ++ exercises, such as simulating the multiplication, printing the amount, checking a set of 3 numbers to see if it is the edge of a triangular triangle, calculating the circumference, area of that triangle.
Gradually, it will be more difficult to create and manage student lists, documents, print or perform other tasks as required by the lesson. Even draw a graph of trigonometric functions.
